HAIR STYLING APPLIANCE BACKGROUND OF THE INVENTION This applicationrelates in general to hair styling appliances, and more particularly toa hair styling appligenerally consisted of a comb or brush combined witha blower and heaterassembly to direct ahot air stream over the hair asit is combed or brushed. While such appliances provide generallysatisfactory results, far better results are obtained when the hair iswetted just prior to applying heat. To this end, atomizers of varioustypes have been incorporated in hair styling appliances to introduce aspray into the air stream prior to its application to the hair.

Unfortunately, previous attempts at incorporating atomizers into hairstyling appliances have presented certain disadvantages. For example,those prior-art designs which incorporated the atomizer together withits water reservoir in the head of the appliance located the blower,.blower motor and electrical heating elements in the handle of theappliance. As a result, the handle had to beundesirably large toaccommodateair flow to the head and had a tendency to becomeuncomfortablyv .hot from the electrical heating coils during extendeduse. When the handle was reduced to a convenient, manageable size, theair passageway throughthe handle to the head was severely restricted anda-motor and blower assembly of marginal capacity were accommodated onlywith great difficulty. This had the effect of reducing airflow and heatoutput, and hence reducing the effectiveness of the hair stylingappliance. Furthermore, because of space limitations the actuator forthe water spray could not be conveniently located in the handle of theseprior-art units,'making their use with one hand inconvenient.

Another drawback of prior art-hair stylers was that they operated withonly 1 of heat output. From a users standpoint this was not satisfactorysince varying conditions of use, suchas hair length, thickness and style,.as well as the users personal preference, called for widely divergentdegrees of heat.

Another problem with certain of the prior-art designs was their use ofintegral water reservoirs, which caused the blower and heater mechanismsof these hair stylers to be exposed to water each time their reservoirswere filled under a running faucet. Furthermore, whenthe spraymechanisms of such stylers became clogged from impurities in the water,their situs within the styler made repair or replacement unnecessarilydifficult and expensive.

Accordingly, it is a general object of the present in vention to providea new and improved spray-type hair styling appliance which provides highair flow and heating capability. A

It is a still more specific object of the present invention to provide aspray-type hair styling appliance having a convenienthandle-mountedtrigger-like actuator for actuation of its spray mechanism.

It is still another specific object of the present invention to providea hair styling appliance which has a removable water spray reservoircontained within the handle of the appliance.

It isa still more specific objectof the present int/ention to provide ahand-held spray-type hair styling appliance wherein the blower forproviding the air stream is in the head portion, and the motor and sprayreservoir are in the handle portion for greater operating efficiencyand'user convenience.

It is a still more specific object of the present invention to provide anew and improved hand-held hair styling appliance which providesmultiple heat levels to accommodate varying conditions of use.

The invention relates to a hair styling appliance of the type whichsimultaneously applies a spray and hot air stream to hair as it iscombed and brushed. The appliance includes a housing comprisingagrip-like handle portion and an enlarged. head portion havinga hairarranging attachment, a fan. and heater assembly disposed within thehead portion for providing a heated air. stream onto the hair arrangingattachment, and a nozzle disposed within the head portion for injectinga mist into the air stream. A motor disposedwithin the handle portion isprovidedfor drivingthe fan. A liquid pump and reservoir are disposedwithin the handle, and

' lever means are provided in the handle portion for actuating the pump.Means extending between the reservoir andpump and the nozzle supplyliquid from the pump to the nozzle.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring to FIG. 1, the hairstyling appliance 20 of FIG. 1 is seen to comprise upper and lowerhousing sections 21 and 22, respectively, which narrow into a griplikehandle portion at one end and widen into a head portion adapted toreceive a removable comb 23 at the other end. An air intake 24comprising a plurality of slots in sections 21 and 22 is provided totake in air for discharge over comb 23 in a manner to be presentlydescribed. A three position high-off-low function switch 25 is providedto facilitate operator control of the hair styler, and a power cord 26is provided for connection to the AC line. An operator-actuabletrigger-like lever 27 is provided for causing a mist or spray to beadded to the air stream as it passes across comb 23, the manner in whichthis is accomplished to be covered presently. 7

Reference is now made to FIG. 2, which shows the bottom of the appliancewith comb 23 removed. A grated air outlet 28 is seen to overly comb 23for the purpose of directing air from a blower within the hair styleracross the comb. At the bottom-center of this outlet a nozzle 29 isprovided for introducing a spray into the air stream. A machine screw 30extends through lower section 22 and is threaded into upper section 21to secure the two sections in tight engagement. I

Comb attachment 23, as shown in FIGS. 3 and 3A, consists of a generallychannular molded body portion, open at one end and having a pair ofopposed guide slots 31 along two opposed walls. These slots engage apair of guide rails 32 on either side of outlet 28 to slid ably securethe comb attachment in position over the port. A plurality of parallelspaced teeth 33 extend downwardly from the bottom of the channel or bodyand alternate brush arrangements with a flat bottom surface could beemployed on the brush attachment.

Referring now to FIGS. 5 and 6, hair styler 20 is seen to include in itshead portion a blower assembly comprising a cylindrical transverse-flowfan 40. The fan is rotatably coupled to a coaxial low voltage commutatortype drive motor 41 in the handle portion of the appliance by means ofan axial drive shaft 42 at oneend, and is supported at its other end bymeans of a shaft 43. The

fan and motor are within body section 22 by means of a plurality ofrubber grommets 44 fitted over annular abutments on either end ofthemotor and over a sleeve bearing 45 on shaft 43. Appropriate support ribsare molded into housing sections 21 and 22 for the purpose of engagingthe grommets and thereby maintaining the fan and motor in properalignment.

Fan 40, as seen in FIG. 7, includes a plurality of Iongitudinalforwardly curved vanes 46 which coact with the overlying vortexstabilizing wall 47 to direct air from inlet 24 to outlet 28. As the fanrotates clockwise it draws air radially inward in the vicinity of inlet24,

. and discharges air radially outward through a different portion toform the comb work area. A plurality of apertures 34 on either side ofthe comb body axis are provided to allow the air stream from outlet 28to freely pass to the comb work area.

A brush attachment 35 is also available for use over outlet 28. As seenin FIGS. 4 and 4A this brush attachment, like comb attachment 23,comprises a generally channular body portion, open at one end and havinga pair of opposed guide slots 36 for engaging rails 32. The bottom ofthe channular body portion is outwardly curved, and has a plurality ofbrush clusters 37 depending perpendicularly in transverse rowstherefrom. A plurality of transverse slots 38 disposed between the brushcluster rows provide for free air circulation between outlet 28 and thebrush work area. It will beappreciated that comb attachment 23 andbrush' attachment 35 can assume other forms depending on the spe-" cificrequirements of the application. For example, multiple rows of combteeth could be employed instead of a single row of comb teeth on thecomb attachment,

section of the fan periphery, in the vicinity of outlet 28. This occursbecause the rotating vanes set up a cylindrical vortex of air justinside the rim of the fan adjacent the vortex stabilizing wall. Thisvortex has an axis parallel to the rotor shaft, and as it is rotated bythe vanes it provides the necessary seal between the suction andpressure sides of the fan. A rectangular duct 48 leads from thedischarge side of the fan to outlet port 28, the vortex stabilizing wall47 being an extension of one of the side walls thereof. This can bebetter seen in FIG. 8, which shows duct 48 and the stabilizing wall inperspective. v

While the transverse fan is ideally suited for this application becauseof the high static pressure it provides with low-speed small-diameterfans, and the particularly well-suited form factor such fans provide inconjunction with a handle-located motor, it will be appreciated thatother types of fans could be used by appropriate modification of theappliance housing.

As seen in FIG. 7 and 8, a pair of flat rectangular heating elements 50and 51 are contained within duct 48 for the purpose of heating the airstream discharged through outlet 28. These heating elements arepreferably aligned edgewise to the air flow, each preferably has atleast one tap for the purpose of controlling the temperature in the airstream in a manner to be presently described.

In accordance with one aspect of the invention, hair styling appliance20 incorporates a water spray system for conveniently injecting a waterspray or mist into the air stream as it is discharged through outlet 28.Referring to FIGS. 10 and 11, water for this system is stored in asemi-cylindrical water reservoir bottle 60. A screwtype cap 61 isthreaded onto the mouth of the bottle. A single stroke liquid pump 62,which may be conventional in design and construction, extends throughthe cap and into the bottle. An additional length of tubing 63 isprovided between the intake end of this pump to insure thatsubstantially the entire contents of the bottle will be available to thepump. As pump 62 extends outside the bottle it abuts against one end ofa pump actuator lever 64.

As shown in FIG. 11, the end of pump actuator lever 64 which abuts pump62 contains a cup-shaped recess 65 for achieving a liquid-tightengagement with a gagement with trigger 27. Trigger 27 extends through aslot provided between the two sections of the housing, the end inengagement with pump actuator lever 64 being transversely enlarged bymeans of opposed pins 69 to preclude that end of the lever from passingthrough the slot. The other end of the lever is pivotally mounted to thebody sections by'means of an opposed pin and socket arrangement similarto that of lever 64.

Pump 62 can be conventional in design and construction, comprising ahousing 70 having an enlarged portion containing a helicalcompressionspring 71 and a slidable plunger 72. A slidable casing 73,coaxial with plunger 72, is fitted over the'plunger betweenthe innerwall of housing 70. and the outer wall of the plunger. This casing isflared outwardly against valve housing-60 at its inner end and necksdown to an aperture 74 at its outside end to provide a seal with gasket66 and to position the plunger within the valve housing. A .check valveis formed at the intake end of the pump chamber by means of ball valvemember 75 which seats against a narrowed portion of the valve housing 70during down strokes of the pump. Another check valve is formed at thedischarge end of the pump by a wall valve member 76, which fits againstthe inwardly tapered discharge end of the plunger to prevent fluid fromreentering the pump chamber during upstrokes.

Casing 73 is loosely fitted within pump housing 70 to provide an airpassageway between the interior of reservoir bottle 60 and thesurrounding atmosphere. This is necessary for operation of the pump,since otherwise no pressure relief would exist and a vacuum would bedeveloped above the liquid remaining in the reservoir. The passageway isformed by means of an aperture 77 contained in the pump housing andpositioned so that the inside flared end of casing 73 'will be betweenthe aperture and the cap while the plunger is at rest in its fullyextended position. This prevents the bottle from r leaking, since theoutwardly tapered edge of casing 73 coacts with valve housing 70 to forman effectiveliquid seal between aperture 72 and the outside of thebottle. When the pump is actuated the tapered end moves to a positionbelow aperture 77, allowing free movement of air between the inside ofthe bottle and the atmosphere.

As shown in FIG. 10, the reservoir bottle 60 is removable from acompartment within the hair styler by means of a door 78 located at thebottom end of the handle portion of the housing. This arrangement isparticularly advantageous, since the reservoir can be removed from theappliance without interference to the hair arranging attachments of thehead, and without exposing any of the internal electrical or mechanicalelements of the appliance. For maximum utilizationsof space within thehandle, reservoir bottle 60 is shaped in the form of a half cylinder,one side wall of its body being arcuate to conform to the inside arcuatesurface of housing section 21, and the other side wall being flat toprovide space within the handle for receiving electrical power cord 26and its associated anchor block, as illustrated in FIG. 9. The arcuatewall of the reservoir bottle may be provided with a plurality ofindentions 79 for the purpose of facilitating the removal of the bottle.Access door 78 is pivotally mounted to housing section 22 by means ofopposed outwardly extending integral pins which coact withcomplimentarily spaced slots on the housing.

It will be appreciated that when reservoir bottle 60 is removed from theappliance cap 61 can be conveniently removed for the purpose of fillingthe bottle. The bottle can be positioned under a running water faucet inperforming the refilling operation, withoug fear of damaging theinternal mechanism of the hair styling appliance. Furthermore, shouldthe pump become clogged from minerals or other impurities in the spraysolution, it can be readily cleaned while thus removed. Also, should thepump become defective, it can be replaced by merely fastening a new pumpand cap assembly to the mouth of the reservoir bottle.

A flexible hose 80 is force fit over the protuberance 67 on the pumpactuator lever 64 to carry liquid from the pump to spray head 19. Thishose extends from the handle portion of the hair styler to the headportion, and is attached to the spray head by means of a force fit overa protuberance provided at the rear of spray head 29. Referring to FIG.7A, spray head 29 com-.

prises a hollow body portion 81 having a protuberance for receiving hose80 and further having a single apertu re82 for developing a fine sprayof mistfrorn the liquid forced into the head from hose 80. Theinnerchamber 83 of the spray head assembly is seen to be annular incross section, having aridge about its inner surface which forms anannular orifice-84 in which the spray is developed.

A pressure relief valve 85 is included in hose near the spray head.Referring to FIGS. 7B and 7C, the pressure relief valve is seen tocomprise a bu|let-shaped member of neoprene or similar materialfrictionally positioned within hose 80. Theforward or downstream end ofthis member is slit into three equal segments 86-88, as seen in FIG. 7C.Since the neoprene is semiflexible, the outwardly convex downstream endof member effectively comprise a trio of flexible hinges. Underpressure, these hinge sections 86.88 expand outwardly, forming anaperture through which fluid can pass. When not under pressure, thenatural resiliency of the neoprene causes the three valve sections toreturn to their closed condition, preventing the flow of fluid throughspray apertures 82 unless a positive force is exerted thereon by pump70.This prevents water trapped withinthe hose from dripping out betweenuses.

As mentioned previously, provision is made in the circuitry of hairstyling appliance 20 for operating at two different heat levels.Referring to FIG. 12, an AC current source, as represented by AC linecord 26, is connected to-the first pole 90 of a .three position twopole.mode switch 91. The other side of the AC line is connected by means of athermal safety switch 92 to one end contact of a resistive heatingelement.93,

- which comprises four individual sections 94-97. The

othervend contact of heating element 93 is connected to the remainingpole 98 of mode switch 91 and thence to the low heat mode contact of thefirst pole of the switch. Resistive heating element 93 includes threetaps 99-101 between sections 94 and 95, 95 and 96, and 96 and 97,respectively. Taps 99 and 101 are connected to the anodes of a pair ofrectifiers 102 and 103, respectively, and the cathodes of theserectifiers are connected together and to one terminal of the DC fanmotor 41. The remaining terminal of motor 41 is connected directly totap 100 on heating element 93. Tap 101 is also connected to the highheat mode contact of pole 90, and the high heat mode contact of pole 98is connected directly to the other side of the AC line.

In operation, when mode switch 91 is positioned for high heat operation,one side of the AC line is connected to both end terminals of theresistive heating element 93. The other side of the AC line is connectedto tap 101, thus connecting segment 97 in parallel with j the seriescombination of segments 94-96, and developing a voltage across segments95 and 96 for application to motor 41. Diodes 102 and 103 rectify thealternating current developed across segments 95 and 96 for the purposeof supplying a direct current to the motor. It will be appreciated thatthe hair styler could employ other types of motors, including AC typemotors by appropriate modification of'the circuit components. Thus, thelow heat mode allows full line current to be applied across section 97of heating element 93, and allows sections 94-96to operate in serieswhile developing a suitable alternating current for motor 41.

When mode switch 91 is positioned for low heat operation, the AC line isconnected across all four sections of heating element 93. Since the lineis not'connected to any one of the taps 99-101, all four sections of theheating element are now in series-circuit relationship'and less currentflows through the heating elements than did in the high heat operatingmode. However, as before fan motor 4l receives its operating power bymeans of the voltage'drop across sections 95 and 96 of' heating element93. Since the current through these sections is less, a lower voltage isapplied to the blower motor 41 and the motor operates at a reducedspeed, typically in the order of 50 percent of its high heat mode speed.7

Thus, a hair styling appliance has been shown and described whichcombines maximum utility with minimum weight and size. This is madepossible by a unique arrangement of components within the appliancehousing. A transverse-flow fan and coactin'g housing are located in thehead portion of the housing for maximum performance and efficiency,while the fan motor is located in the handle portion of the housingwherein its relatively modest size requirement is easily accommodatedwithin the narrow confines of a conveniently sized handle. Adjacent themotor within the handle, a unique trigger-actuated pump is provided toforce water from a reservoir bottle within the handle to a containedwithin the handle which would render it uncomfortably hot to the touch,the heating elements for the air stream being contained entirely withinthehead for maximum separation from the user and maximum efficiency inheating the air stream.

While a particular embodiment of the invention has been shown anddescribed, it will be obvious to those skilled in the art that changesand modifications may be made without departing from the invention inits broader aspects, and, therefore, the aim in the appended claims isto cover all such changes and modifications as fall within the truespirit and scope of the invention.
